mfc对控件画背景图

mfc对控件画背景图

// 创建画刷

m_hredbrush = createsolidbrush(rgb(255, 0, 0));

m_hgreenbrush = createsolidbrush(rgb(0, 255, 0));

m_hsourcebrush = createsolidbrush(rgb(240, 240, 240));

初始化控件样式

((cstatic*)getdlgitem(idc_static_zj))->modifystyle(0, ws_border | ss_blackframe | ss_blackrect);

//((cstatic*)getdlgitem(idc_static_zj))->invalidate(true);

((cstatic*)getdlgitem(idc_static_laser))->modifystyle(0, ws_border | ss_blackframe | ss_blackrect);

//((cstatic*)getdlgitem(idc_static_laser))->invalidate(true);

((cstatic*)getdlgitem(idc_static_jxwd2))->modifystyle(0, ws_border | ss_blackframe | ss_blackrect);

重绘控件时的样式

((cstatic*)getdlgitem(idc_static_zj))->modifystyle(ws_border | ss_blackframe | ss_blackrect, 0);

((cstatic*)getdlgitem(idc_static_zj))->invalidate(true);

((cstatic*)getdlgitem(idc_static_laser))->modifystyle(ws_border | ss_blackframe | ss_blackrect, 0);

((cstatic*)getdlgitem(idc_static_laser))->invalidate(true);

((cstatic*)getdlgitem(idc_static_jxwd2))->modifystyle(ws_border | ss_blackframe | ss_blackrect, 0);

((cstatic*)getdlgitem(idc_static_jxwd2))->invalidate(true);

2使用画刷

hbrush czkmonitordlg::onctlcolor(cdc* pdc, cwnd* pwnd, uint nctlcolor)

{

hbrush hbr = cdialogex::onctlcolor(pdc, pwnd, nctlcolor);

// 激光器

if ( pwnd->getdlgctrlid() == idc_static_laser )

{

//pwnd->setwindowtextw(_t(""));

switch (lasercheckstatedata)

{

case emnone:

{

/*m_sourcecolorref = pdc->getdcbrushcolor;*/

//pdc->setbkcolor(m_hsourcebrush);

//pdc->setbkcolor(pdc->setbkcolor(m_sourcecolorref););

//pdc->setbkcolor(rgb(120, 120, 120));

//pdc->setbkmode(transparent);

hbr = m_hsourcebrush;

break;

}

case emok:

{

//pdc->setbkcolor(rgb(255,0,0));

//pdc->setbkmode(transparent);

hbr = m_hgreenbrush ;

break;

}

case emerror:

{

//pdc->setbkcolor(rgb(0, 255, 0));

//pdc->setbkmode(transparent);

hbr = m_hredbrush;

break;

}

default:

break;

}

}

// 振镜

if ( pwnd->getdlgctrlid() == idc_static_zj )

{

//pwnd->setwindowtextw(_t(""));

switch (zjcheckstatedata)

{

case emnone:

{

//pdc->setbkcolor(m_sourcecolorref);

//pdc->setbkcolor(rgb(240, 240, 240));

//pdc->setbkmode(transparent);

//hbr = m_hsourcebrush;

break;

}

case emok:

{

//pdc->setbkcolor(rgb(255, 0, 0));

//pdc->setbkmode(transparent);

hbr = m_hgreenbrush ;

break;

}

case emerror:

{

//pdc->setbkcolor(rgb(0, 255, 0));

//pdc->setbkmode(transparent);

hbr = m_hredbrush;

break;

}

default:

break;

}

}

// 机箱温度

if (pwnd->getdlgctrlid() == idc_static_jxwd2)

{

switch (tmpcheckstatedata)

{

case emnone:

{

//pdc->setbkcolor(m_sourcecolorref);

//pdc->setbkcolor(rgb(240, 240, 240));

//pdc->setbkmode(transparent);

hbr = m_hsourcebrush;

break;

}

case emok:

{

//pdc->setbkcolor(rgb(255, 0, 0));

//pdc->setbkmode(transparent);

hbr = m_hgreenbrush;

break;

}

case emerror:

{

//pdc->setbkcolor(rgb(0, 255, 0));

//pdc->setbkmode(transparent);

hbr = m_hredbrush;

break;

}

default:

break;

}

}

// todo: change any attributes of the dc here

// todo: return a different brush if the default is not desired

return hbr;

}

3 删除画刷，在类的析构函数中调用

deleteobject(m_hredbrush);

deleteobject(m_hgreenbrush);

deleteobject(m_hsourcebrush);
